This is another task. If you already have data formatted into strings,
then of course these can be written directly to a file. But for that you
don't need a C++ std::ostream interface, you can write directly into the
file descriptor, or C++ streambuf(). If there are only a handful of
strings, then you can of course write them to the stream as well, the
overhead is insignificant.
What I'm talking is about outstreaming millions of small items
one-by-one, like advocated by ostream<< enthusiasts: just define a
proper operator<< overload and write everything in the ostream,
recursively, each number separately.
It's this formatting interface of C++ iostreams which is slow. With
MSVC++ I just stepped though an operator<<(std::ofstream&, int), this
involved at least 2 virtual function calls, 4 locking/unlocking of
current locale, and consulting TLS about the number of uncaught
exceptions, not to speak about tens of non-virtual function calls (which
hopefully get optimized away) and twiddling with the stream state. This
is all 100% unnecessary overhead for formatting an int in C locale. It
won't matter for a single debug printout line, but it will matter when
exporting a 100,000 line table into a CSV file.

No, of course not.
